Purpose: To provide clinicians in primary care settings information on the effects of sleep-disordered breathing in patients with heart failure (HF). Assessment and screening tools, as well as management considerations, are presented.
Data Sources: Review of the scientific literature of the past 10 years, along with classic studies and Internet sources.
Conclusions: HF is an increasingly prevalent problem with a high degree of associated sleep-disordered breathing. There are two broad categories of sleep-disordered breathing: obstructive sleep apnea and central sleep apnea/Cheyne-Stokes breathing. Both of these occur on a continuum of mild hypopnea to severe apnea with hypoxia. Sleep apneas are particularly harmful to patients with HF and, if left untreated, may adversely affect their prognosis. Yet sleep apnea is not routinely screened for in this population.
Implications For Practice: Given the serious consequences of untreated sleep-disordered breathing, there is sound justification to screen for sleep apnea in all patients with HF. Subsequent treatment of those patients with sleep apnea can significantly improve their quality of life and can decrease their mortality.

Purpose: Children with achondroplasia (ACH) are at risk for sudden death in infancy due to sleep disordered breathing (SDB) and foramen magnum stenosis (FMS). Sleep studies and neuroimaging are performed in infants with ACH, but interpretation of infant studies is challenging. We sought to describe baseline data on polysomnography (PSG) indices in infants with achondroplasia as well as effects of age and surgery on these parameters.

Sleep apnea-hypopnea syndrome (SAHS) is a respiratory disorder characterized by cessation of breathing during sleep, resulting in daytime somnolence and various comorbidities. SAHS encompasses obstructive sleep apnea (OSA), caused by upper airway obstruction, and central sleep apnea (CSA), resulting from lack of brainstem signaling for respiration. Continuous positive airway pressure (CPAP) therapy is the gold standard treatment for SAHS, reducing apnea and hypopnea episodes by providing continuous airflow.

The Alertapnée study followed 555 adults with obstructive sleep apnea treated with CPAP and found that the occurrence of Cheyne-Stokes respiration (CSR) was linked to a 14-fold increase in the risk of significant cardiac events (SCE) after one year. However, the progression and clinical significance of CSR episodes over time remain unclear. This ancillary study aimed to assess CSR progression and clinical outcomes during a second year of follow-up in 66 patients who had experienced at least one CSR episode in the first year.

Purpose: The expression of the respiratory events in OSA is influenced by different mechanisms. In particular, REM sleep can highly increase the occurrence of events in a subset of OSA patients, a condition dubbed REM-OSA (often defined as an AHI 2 times higher in REM than NREM sleep). However, a proper characterization of REM-OSA and its pathological sequelae is still inadequate, partly because of limitations in the current definitions.

Background: This study aimed to investigate the association between Obstructive Sleep Apnea (OSA) and Tinnitus using NHANES data from 2005 to 2020.
Methods: This study analyzed data from NHANES (National Health and Nutrition Examination Surveys) conducted between 2005 and 2020, and included 4871 participants aged 16 or older. OSA was assessed using the Multivariate Apnea Prediction Index and the variables from the National Health and Nutrition Examination Survey.
